A colleague of mine just called, having done an “erase flash” on a 3750. He did this because there was only 16MB of flash on the switch and therefore not enough room for two images at the same time. What he didn’t expect was that the switch would subsequently reboot and end up in bootloader mode with no software on it…

So here’s what we did. I thought I’d write this up because I found it a bit difficult locating the information on Cisco.com.
